Even if the EC or Owners Corp weren’t aware, I am advised that the Owners Corp’s legal responsibility for common property trumps the ‘buyer beware’ principal of property purchases. In other words, it’s an Owners Corp cost. The fact that they were aware merely means they need a stern talking to at your next AGM.
Downlights are becoming very popular in apartments (because of low ceilings). The Owners Corp needs to put through a by-law that says that downlights and their fittings must be installed by approved electricians and that all future maintenance and costs are attributable to the lot owner, regardless of whether they received permission or not.
